Schematic reviews are a part of the hardware development cycle in many if not most, hardware development companies. Typically led by the electrical engineering team, it is easy to overlook design issues that will be important to the firmware team. This post tells of a few stories of design misses that I have made and puts some common lessons learned into a checklist for other firmware engineers.

NVIDIA offers one of the most comprehensive SDKs for developers of AI-heavy products. It includes a development kit that can emulate other devices in the lineup (Jetson AGX Orin DK), a simpler development kit for “entry-level” products (Jetson Orin Nano DK), a ton of exciting software libraries, AI models and even more examples of how to use them. It’s truly outstanding and out of the box shows up as a Ubuntu workstation which will feel very familiar.

In previous articles, we have considered the primary uses of JTAG, including debugging and testing boards in production. For firmware developers, the first - debugging - is the most common. In this article, I want to look at two uses of JTAG Boundary Scan, which are also common tasks for a firmware developer: board bring-up and reverse engineering. Like Interrupt?

In the previous articles, we used freestanding applications and relied on a global Zephyr installation. In this article, we’ll see how we can use West to resolve global dependencies by using workspace applications. We first explore West without even including Zephyr and then recreate the modified Blinky application from the previous article in a West workspace.

April marked the return of the Embedded Open-Source Summit, this year in Seattle. I was lucky enough to be able to attend and split my time between the Memfault booth in the exposition hall and many of the captivating presentations. Since the videos have just been published on the the Linux Foundation’s YouTube account, we thought it would be a good time to highlight some of the talks and give you a quick summary which will, hopefully, inspire you to go watch them!

Earlier this month, I had the pleasure of traveling to Nuremberg, Germany to attend Embedded World. If you have not heard about it before, Embedded World1 is the largest trade show in the embedded systems industry. This year, over 35,000 people attended and 1,100 businesses exhibited at the Nuremberg Messe.

In the previous articles, we covered Devicetree in great detail: We’ve seen how we can create our own nodes, we’ve seen the supported property types, we know what bindings are, and we’ve seen how to access the Devicetree using Zephyr’s devicetree.h API. In this fifth article of the Practical Zephyr series, we’ll look at how Devicetree is used in practice by dissecting the Blinky application.

In the previous article of this series, we briefly touched on how.bsd files written in Boundary Scan Description Language (BSDL) describe the structure of the boundary scan chain and the instruction set. In this article, we will examine this language’s syntax more closely before seeing how.bsd files are leveraged in JTAG testing in the next article.

In the third installment of this JTAG deep dive series, we will talk in-depth about JTAG Boundary-Scan, a method used to test interconnects on PCBs and internal IC sub-blocks. It is defined in the IEEE 1149.1 standard. I recommend reading Part 1 & Part 2 of the series to get a good background on debugging with JTAG before jumping into this one!

Reduce risk, ship products faster, and resolve issues proactively by upgrading your Android and MCU-based devices with Memfault. By integrating Memfault into smart device infrastructure, developers and IoT device manufacturers can monitor and manage the entire device lifecycle, from development to feature updates, with ease and speed.
With Memfault, engineers no longer have to rely on incomplete user crash reports and their local debugger to reproduce and fix device issues in the field. Memfault's cloud-based firmware delivery, monitoring, and analytics tools dramatically reduce engineering and support overhead, enabling you to ship and manage thousands to millions of IoT devices with confidence./p>
One platform for more efficient device operations:
- Continuously monitor devices: Go beyond application monitoring with device and fleet-level metrics, like battery health and connectivity with crash analytics for firmware.
- Remotely debug firmware issues: Resolve issues more efficiently with automatic detection, alerts, deduplication, and actionable insights sent via the cloud.
- Systematically deploy OTA updates: Keep customers happy by fixing bugs quickly and shipping features more frequently with staged rollouts and specific device groups (cohorts).
Cloud Debugging and Observability for Your IoT Devices.
